How would you like to wake up to this guy staring at you? You wouldn't, would you? Okay, how about the guy with the phone? I give him a maybe. Anyway, some scientists (the smart ones) fear that robot intelligence is going too far and we must do something to stop them before they stop (read: kill) us.

Impressed and alarmed by advances in artificial intelligence, a group of computer scientists is debating whether there should be limits on research that might lead to loss of human control over computer-based systems that carry a growing share of society's workload, from waging war to chatting with customers on the phone.

[They] generally discounted the possibility of highly centralized superintelligences and the idea that intelligence might spring spontaneously from the Internet. But they agreed that robots that can kill autonomously are either already here or will be soon.
